Atoms anyone?

1. What has the mass of Everest but the diameter of an atom?

2. Is an atom affected by gravity?

3. Krypton has an atomic weight of 83.80 and atomic number of 36. What happens if you remove a proton from this element?

4. Hydrogen atoms are small. Electrons are smaller. How many electrons does it take to equal the size of one hydrogen atom?

5. Why and what phenomenon causes a nuclear reactor to glow a brilliant blue?

6. Who is uud?

7. Who is ddu?

8. Can you think of 2 examples whereby you can find crushed atoms?

9. What is this element?

10. What is plumbum?

3 - Bromine Isotope?

Yes. Removing one(1) proton from an atom of Krypton (36 protons) results in an atom of Bromine (Br) - Atomic weight of 79.904; 35 protons (atomic number).
Excellent...

1. Neutron Stars Are Atoms the Size of Mountains

5. Why and what phenomenon causes a nuclear reactor to glow a brilliant blue?

Cherenkov radiation, also known as Vavilov-Cherenkov radiation,[a] is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. The characteristic blue glow of an underwater nuclear reactor is due to Cherenkov radiation. It is named after Soviet scientist Pavel Alekseyevich Cherenkov, the 1958 Nobel Prize winner who was the first to detect it experimentally.[1]

1. Neutron Stars Are Atoms the Size of Mountains
Just a little misunderstanding of the question: What is the size of the diameter of an atom, but weighs as much as Mt. Everest...

5. Why and what phenomenon causes a nuclear reactor to glow a brilliant blue?

Alana33: :Cherenkov radiation, also known as Vavilov-Cherenkov radiation,[a] is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. The characteristic blue glow of an underwater nuclear reactor is due to Cherenkov radiation.

Yes! Cherenkov Radiation. In the nuclear reactor example and being non-vacuum - the medium is, of course, water. The shortest wavelength of visible light is blue; hence the beautiful blue glow. Some tend to define this phenomenon as a 'light-based sonic boom'.

Yes! Those mini black holes that science insists are hanging around, yet haven't been proven to exist. My keys, some pens, a favorite mug are still missing and I insist it is because I have a mini black hole here in the house!

Just a thought?

“A human being is a part of the whole called by us universe, a part limited in time and space. He experiences himself, his thoughts and feeling as something separated from the rest, a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.” ------------------------------Albert Einstein

1. It is considered the largest museum on Earth.

The Smithsonian - JJ

It is certainly a large one; but to be fair, I should have been clearer and said that the answer wasn't going to be a building. My question was very vague and I apologize. The answer to this was "the ocean" is the largest, because it contains the most remnants and artifacts than all the museums combined. I'm sorry for not being clearer. Very good answer, JJ!

2. At springtide in this location, the difference between low tide and high tide is 53 1/2 feet.

The Bay of Fundy - JJ.

Yes! Located between New Brunswick & Nova Scotia, Canada.

3. Four times longer than the Andes, Himalayas, and Rocky Mts. combined, it is Earth's longest mountain range.

The Mid Ocean ridge - JJ.

Yes! It runs from the Arctic, to Atlantic, skirts Africa, Asia, Australia, crosses the Pacific, and ends at the west coast of North America.

4. This country has the longest coastline.

Canada - JJ.

Yes! Canada.

5. This percentage of the Earth's surface is covered by oceans, containing 97% of the Earth's total amount of water.

71% - JJ.

Yes! 71%.

Questions for Kids:

6. What ocean's name means "Peaceful Sea?"

The Pacific Ocean - JJ.

Yes!

7. Covering 30% of the Earth's surface, what is the Earth's largest ocean?

Yes!

8. Covering 21% of the Earth's surface, what is the Earth's 2nd. largest ocean?

The Atlantic Ocean. - JJ

Yes!

9. Covering 14% of the Earth's surface, what is the Earth's 3rd. largest ocean?

The Indian Ocean - JJ

Yes!

10. What is the largest "fish" in the world?

The Whale Shark - JJ.

Yes!. It's length is 40feet!

11. What is the fastest fish in the world, attaining speeds up to 68mph for over 300 meters?

The Sailfish - JJ

Yes!

12. The rainforests are the most diversified of ecosystems on the planet; where would you find such a vastly diversified ecosystem in the ocean?

A coral reef. - JJ.

Yes! Coral Reefs!

JJ (dougtamjj) you were OUTSTANDING and answered all the questions correctly! Congratulations, my special friend!

The magnificent Coral Reefs anyone?

1. Belonging to the Kingdom Animalia and the Phylum Cnidaria, to what two other Groups do Coral belong?

2. What is a group of Coral called?

3. About how many years ago were the earth's Coral Reefs formed?

4. Consisting of a stomach and tentacle-bearing mouth, what is an individual Coral known as?

5. An individual Coral exudes an exoskeleton beneath it and, over time, this leads to the formation of the Coral Reef: What is the name of the chemical compound called in which the Coral exudes beneath it?

6. Where do Corals get their color from?

7. Consisting of 3,000 smaller reefs and covering 350,000 sq.km (210,000 sq. miles), what is the largest Coral Reef on Earth?

8. Found in a large range of colors and shapes, what are the 3 "major" types of Coral Reefs that exist?

9. Why are Coral Reefs important and what do they contribute toward marine biodiversity?

10. Although many causes are responsible for creating negative impacts, can you name 3 "threats" that are posing a danger to survival of Coral Reefs?
